What does this mean? high cholesterol??

I got blood work done yesterday. and I was advised that I’m an overall healthy man…. (fasting before test) My glucose level is 96, and normal is between 70-99, my blood pressure was 118/70 and my pulse was 64 and normal pressure is <120/<80, and normal pressure is 60-100....... now my Total choleserol level was 137mg and my triglicerides was 99, normal is less than 150.... but my HDL was very LOW, less than 15???? and the machine couldnt read my LDL. I'm concerened. I'm a 25 yr old african american male. should i go and be retsted ???
can someone please just answer my question... plz dont attempt to answer by stating the same stats that i just posted.... if u dont know the answer to my question than jst move on!!!!

I would suggest speaking with your doctor as soon as possible and asking for a retest. Your doctor could give you a better understanding of your LDL levels, but your Low HDL puts you at risk for heart disease. The fact that your LDL doesn’t even register makes me wonder about the other results.
